Bottom Line: No other significant group × time interactions were found.SD supplementation for 30 days significantly improved best drive distance more than placebo.Supplementation was well tolerated and did not result in any clinically significant changes in markers of health or adverse events/side effect profiles.

ABSTRACT

Background: Limited research exists examining the impact of nutrition on golfing performance. This study's purpose was to determine the impact of daily supplementation with an over-the-counter dietary supplement on golf performance.

Methods: Healthy men (30.3 ± 6.9 y, 183.1 ± 5.6 cm, 86.7 ± 11.9 kg), with a 5-15 handicap were assigned in a double-blind, placebo-controlled manner to ingest for 30 days either a placebo (PLA, n = 13) or a dietary supplement containing creatine monohydrate, coffea arabica fruit extract, calcium fructoborate and vitamin D (Strong Drive™, SD, n = 14). Subjects ingested two daily doses for the first two weeks and one daily dose for the remaining two weeks. Participants followed their normal dietary habits and did not change their physical activity patterns. Two identical testing sessions in a pre/post fashion were completed consisting of a fasting blood sample, anthropometric measurements, 1-RM bench press, upper body power and golf swing performance using their driver and 7-iron. Data were analyzed using two-way mixed factorial ANOVAs and ANCOVA when baseline differences were present. Statistical significance was established a priori at p ≤ 0.05.

Results: ANCOVA revealed significantly greater (post-test) best drive distance (p = 0.04) for SD (+5.0% [+13.6 yards], ES = 0.75) as well as a tendency (p = 0.07) for average drive distance to increase (+8.4% [+19.6 yards], ES = 0.65), while no such changes were found with PLA (-0.5% [-1.2 yards], ES = 0.04 and +1.3% [+2.8 yards], ES = 0.08, respectively). Both groups experienced significant increases in body mass and 1-RM bench press (p < 0.001). No other significant group × time interactions were found. For the SD group only, within-group analysis confirmed significant improvements in set 1 average (+8.9%, p = 0.001) and peak velocity (+6.8%, p < =0.01). No changes were noted for reported adverse events, pain inventories, quality of life or any measured blood parameter.

Conclusions: SD supplementation for 30 days significantly improved best drive distance more than placebo. Supplementation was well tolerated and did not result in any clinically significant changes in markers of health or adverse events/side effect profiles.

Mentions: In a double-blind, placebo-controlled fashion, study participants were instructed to ingest either a powdered dietary supplement containing creatine, coffea arabica fruit extract (CoffeeBerry®), calcium fructoborate (FruiteX-B®) and vitamin D (Strong Drive™, SD, n = 14) or an isocaloric placebo (PLA, n = 13). A representative Supplement Facts label of the investigational product is shown in Figure 1. Irrespective of group assignment, all study participants were instructed to take each serving of their assigned supplement with eight ounces of cold water. For the first two weeks of the study, one serving was consumed twice per day (with breakfast and lunch). During the final two weeks of the study, study participants consumed only one serving per day of their assigned supplement (with breakfast). This protocol was employed to match manufacturer guidelines; the protocol also corresponded with previous creatine supplementation literature showing effective increases in intramuscular creatine and phosphocreatine levels [3,6]. To ensure complete blinding, all study supplements were in powder form of similar color, texture and flavor while also being packaged in coded generic containers. Compliance to the supplementation protocol was monitored by having study participants complete a supplementation log. In addition, study participants were required to return their empty supplement containers and were reminded of details associated with the study protocols with weekly text messages and/or emails. Participants were instructed to refrain from using other supplemental courses of caffeine or creatine.Figure 1
